In the past few weeks on signon to my PC I have noticed the error that KBDIBOC.dll cannot be found. I have tried to find this on the internet but it also can't br found. Does anyone know what this file is and how I can fix the error.

Hello, based on internet searches, I don't see that this DLL file belongs to Microsoft Windows. It is possible then that it belongs to a malware program. Please perform a full scan on your disks and uninstall all malware programs. Once done, perform a repair install of your OS.

Not being able to find a dll file with a web search is a very strong indication that its name was randomly generated by a malware program. Did you remove any malware recently? If so, it's likely that although the malware was removed, a reference to it was left; if so you should remove the reference to it which you should be able to find in MSCONFIG.EXE Ken Blake, Microsoft MVP
